The Myth of Big, Bad Gluten
As many as one in three Americans tries to avoid gluten, a protein found in wheat, barley and rye. Gluten-free menus, gluten-free labels and gluten-free guests at summer dinners have proliferated.
Some of the anti-glutenists argue that we haven’t eaten wheat for long enough to adapt to it as a species. Agriculture began just 12,000 years ago, not enough time for our bodies, which evolved over millions of years, primarily in Africa, to adjust. According to this theory, we’re intrinsically hunter-gatherers, not bread-eaters. If exposed to gluten, some of us will develop celiac disease or gluten intolerance, or we’ll simply feel lousy.
Most of these assertions, however, are contradicted by significant evidence, and distract us from our actual problem: an immune system that has become overly sensitive.
